1 Claim.

The present invention relates to chenille yarn and has as its principalobject the provision of a chenille yarn which is elastic so that it maybe stretched longitudinally. The invention contemplates the provision-ofa chenille yarn which, because of its longitudinal elasticity, has thechenille thread or transversely extending fibers compressed together .soas to provide a good body that is much more full than ordinary chenille,yarn.

The advantages of the present invention are particularly noticeable whenthe chenille yarn is made upinto fabrics, as it imparts to the fabric anelasticity in all directions so that a garment made of this chenilleyarn may stretch and return to its original shape in a manner which hasnot heretofore been possible.

The present invention is applicable to chenille yarn, whether made bythe weaving or twisting principle. Furthermore, it applies equally wellto out and uncut chenille yarn, as will be readily understood from thefollowing disclosure. The materials which are used as chenille thread,or weft thread, may be any of the known textile or fibrous materialssuch for example as wool, silk, cotton, rayon, cellulose acetate, hemp,jute or hair. For the core strands of the yarn I may use elastic threadsof any suitable construction, either with or without added strands ofnonelastic material.

Thev features and advantages of the invention will appear more fully asthe description proceeds,

reference being had to the accompanying drawing wherein a preferredexample of the invention is shown. It is to be understood, however, thatthe drawing'and description are illustrative only and are not to betaken as limiting the invention except insofar as it is limited by theclaim.

In the drawing, Fig, 1 is a somewhat diagrammatic view illustrating thecore strands or warp used in the chenille yarn; 1

Fig. 2 is a view showing how the chenille filler or weft thread is Wovenbetween the core strands and cut to produce chenille yarn; and 7 Figs.3, 4 and 5 are cross sectional views illustrating chenille yarn withvarying amounts of elastic material incorporated therein.

In making the chenille yarn, whether it is made by weaving or twisting,I prefer to take the core or warp strands'shown at 6, I, 8 and 9 in Fig.1 and stretch the elastic strands which are considerably shorter thanthe non-elastic strands before weaving in the filler threads. In Fig. 1the strands I and 9 are elastic, being preferably 5 composed of rubberwhich may or may not be wrapped'with a covering. of a fine textilethread. The warp strands 6 and 8 are of any non-elastic material such asany of the materials used as weft threads.

. In weaving the chenille yarn I stretch the elastic strands of the coreor warp until they are under considerable tension, and then weave in thefiller or weft material in the usual fashion. The groups of core strandsare then separated by cutting the filler material between the groups toproduce chenille yarn. I have illustrated the manner of weaving chenilleyarn, althoughit is obvious'that twisted chenille yarn could also bemade with one or more elastic core strands. In Fig. 3 I have shown incross section a chenille yarn in which two of the core strands arerubber and two of the core strands are textile. In Fig. 4

all of the core strands are of rubber, and in Fig. 5 only one corestrand is of rubber. In all forms of producing the chenille yarn,however, it is prefe erable that the elastic core strands be stretchedduring the formation of the yarn, so that when the yarn is completed thetendency of the elastic strands to return to their original length willcompress the filler threads and make a full-bodied chenille yarn. In theyarn as completed the nonelastic threads will of course be loose andfree of tension, so that the yarn is not still or unwieldy. The elasticstrands, however, remain under some tension due to the opposition of thefiller material to their return to original length. The resultingproduct is an elastic chenille yarn in which the filler or weftmaterials are closely packed and held together under tension by the 4elasticity of the core strands.

Having thus described my invention what I desire to claim. as new andsecure by Letters Patent is: v

A chenille yarn having core strands, certain of said core strands beingelastic and under tension whereby the yarn is compressed longitudinallyand may be stretched.
